Spree 2.0 is coming soon. Read this blog post by @LBRapid explaining one of its best features.

We’ve been grappling with the issue of complex Spree stores that require sophisticated shipping and warehouse logic for several years now. While it has always been manageable to get this to work on individual store basis, a more general solution that would be useful for all stores has always eluded us (until now). We are proud to introduce the new split shipments functionality to Spree! This feature is available to try out on the master branch of Spree and will be included in the upcoming Spree 2.0 release. Sean Schofield, the creator of Spree, will go into depth about the new features included in Spree 2.0 including split shipments, the re-architecture of the Spree core and internationalization improvements at SpreeConf May 20th – 21st in Washington, DC.
